Manly P. Hall was the preeminent philosopher of the 20th century who lectured for over 70 years to make ancient wisdom and obscure esoteric knowledge available for all truth seekers.
He is perhaps best known for his magnum opus, The Secret Teachings of All Ages, an elaborately illustrated encyclopedia of Western mystery traditions, secret societies and symbolic philosophy.
Many of his 7,000 public talks were recorded, transcribed and published. He penned over 150 books on philosophy, religion and science, with the goal of helping each individual to learn, grow and build for themselves a practical philosophy of life.
Beginning in 1919 at the age of 18, Hall’s public speaking career would continue for the next 71 years. He started the Philosophical Research Society (PRS) in 1934, and opened a wisdom library with thousands of texts, rare books and priceless artifacts. In 1959, a 300 seat auditorium was constructed at headquarters in Los Angeles, where he would lecture regularly for the next 30 years.
